- n. The ultimate standard of mass in the French system of weights and measures, equal to 1,000 grams; the mass of a certain cylinder of platinum deposited in the Archives of France on the 22d of June, 1799, and thence known as the Kilogramme des Archives. But in future the ultimate standard will be the international kilogram at the Pavilion de Breteuil near Sèvres; this substitution will not alter the value of the kilogram. The kilogram was intended to be (and is, within one ten-thousandth part) the mass of a cubic decimeter of water at its maximum density. It was ascertained by Miller to be equal to 15432. 34874 grains, or 2. 20462125 imperial pounds, with a probable error of 3 in the last decimal place. An independent determination by Miller (made merely as a check upon the other) gave 2. 20462116, with a probable error of 5 in the last place. The real error, however, and indeed the variations of weight of this ill-constructed Kilogramme des Archives, may very likely be somewhat greater. See

- n. In the International System of Units, the base unit of mass; the mass of a specific cylinder of platinum-iridium alloy kept at the International Bureau of Weights and Measures in France. Symbol: kg
- n. proscribed Hence, the unit of weight such that one-kilogram mass is also a one-kilogram weight.

- n. A measure of weight, being a thousand grams, equal to 2.2046226 pounds avoirdupois (15,432.34 grains). It is equal to the weight of a cubic decimeter of distilled water at the temperature of maximum density, or 39° Fahrenheit.
- n. one thousand grams; the basic unit of mass adopted under the Systeme International d'Unites
- From French kilogramme, composed of kilo- + gramme. (Wiktionary)
“The precise measure of a kilogram is a weighty matter to some people.”
“Since a kilogram is 1000 grams and a daily intake of lactitol is given as 10 grams, the amount of protein in an average daily serving of lactitol is therefore 32 micrograms of casein and 97 micrograms for lactoglobulin.”
“One kilogram is probably close to the mass of that first stone used to help kill that first antelope, so very long ago.”
“The kilogram is the last of the fundamental SI units to be defined in terms of a physical artefact, and both sites discuss possible alternatives.”
“The kilogram is the only unit not defined off a physical constant – it’s defined from this particular object, the 130-year-old International Prototype Kilogram or IPK.”
“Unit of mass kilogram The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.”
“If you provide 30 grams in the diet, the body gets the other 100 grams from lean mass breakdown. 100 grams times 10 days equals one kilogram, which is 2.2 pounds.”
